Best Online Roulette Bonus Offers & Promotions in 2025

Generous bonus offers from online casinos are a real highlight, and if those platforms offer your favorite games, even better.

Most of us love the excitement of the spinning roulette wheel, so here we focus on the best online roulette bonus offers. Roulette is fun and easy to understand, offering plenty of betting options to suit beginners and high rollers alike. 

If you're lucky enough to land a bonus, there are many new types of roulette games to try. Games include RNG-based video titles and live-streamed real-dealer games filmed in luxurious casino studios.

Below, we discuss online roulette casino bonuses and how, if you’re living in a state where online gambling is permitted, you can claim one of these exciting offers for yourself. 

Types of Online Casino Bonus

Most of you will be familiar with welcome bonus packages offered by online casinos to attract new players. They’re one-off offers available when you initially sign up for an account. They usually consist of a deposit match in bonus funds, free spins, rewards points, or a combination of these rewards. 

Free spins are another common bonus that’s linked to specific slot titles or groups of slots. They can be awarded as part of a package or in ongoing or seasonal promotions offered to returning players.

Deposit matches, or reload bonuses, are when operators match a portion of your deposit in bonus funds. These funds, like those offered in a welcome bonus, often have wagering requirements, meaning you must wager the funds on games like roulette before making any withdrawals.

There are also promotions like refer-a-friend offers and loyalty schemes with even more rewards. Regardless of the type of bonus, it’s important to always read the T&Cs before claiming to ensure you understand the wagering requirements, validity periods, and game restrictions.

BetMGM Casino

BetMGM is one of our all-time favorite brands in the US; it’s backed by years of experience delivering some of the best casino experiences at iconic venues like the MGM Grand and Bellagio in Las Vegas. 

The venue features roulette games in its lobby, including exclusive live casino titles linked directly to games on the casino floor in some of its most well-known Las Vegas venues. You can play with fellow players in social settings or at your own pace on RNG-based titles. 

Casino bonuses at BetMGM include a multi-part welcome bonus with up to $1,000 deposit match, slots tournaments, a refer-a-friend bonus, and an exciting rewards program to redeem points for real-world rewards. 

BetRivers Casino

BetRivers Casino is another favorite among players in US online gambling states. It offers a number of video titles and live dealer roulette from Evolution Gaming and Playtech. Much like BetMGM, BetRivers also offers exclusive titles, but at the time of writing, they didn’t extend to roulette games. 

The welcome bonus at BetRivers is a bonus cash offer of up to $500 of your losses back from your first 24 hours of play. The bonus funds, unfortunately, cannot be used to play roulette, but there are heaps of other options to explore. 

The operator also features sportsbook bonuses, tournaments, seasonal specials, and a generous multi-tiered loyalty program that rewards you with more prizes the more you play. 

FanDuel

You can enjoy a selection of specialist roulette games at FanDuel Casino, once again covering RNG video titles and immersive live dealer games. Highlights include Evolution’s First Person Lightning Roulette and Mega Fire Blaze Roulette from Playtech, which features the developer’s iconic Mega Fire Blaze bonus. 

The welcome bonus for new players at FanDuel Casino is a $100 bonus in casino cash awarded when you sign up, place your first deposit of $5 or more, and wager your first dollar. There is only a low 1x wagering attached to your bonus funds, which you have 7 days to complete, something that should be no drama at all.
